Re: What are current plans for RMCL?

Clozure doesn't have plans to do more work on RMCL.  If someone wanted to hire to do some work on it we'd be happy to speak with them, but it's not clear that there's anything helpful to do.  The fact is that RMCL (and MCL) run on PowerPC and use Carbon, and both those technologies have been deprecated.

It should be possible to reimplement the highest level portions of the MCL Macintosh interface in CCL ---- things like MAKE-WINDOW and MAKE-MENU-ITEM.  But this would still be a long way from creating compatibility with existing MCL source code.

Since the switch to OS X 10.7, there is no default support for old PowerPC applications on OS X anymore, so RMCL doesn't work anymore, at least not without a major effort. Are there any plans to find a remedy for this situation? Or will RMCL effectively become deprecated?

However, the current maintainers of ASDF have an unjustified very low regard for logical pathnames, which causes a lot of pain - basically, whenever a new version of a Common Lisp implementation comes bundled with a new ASDF version, I have to deal with bugs in ASDF that in one way or the other break my setup with logical pathnames.

RMCL would be the only Common Lisp implementation that would cause a problem in this regard.
